20ga sheet metal with Syncrowave 250?

admin

Hi. I just bought my first tig welder- a used Miller Syncrowave 250. Is this machine good for butt welding thin sheet mild steel such a 20 ga?Thanks!
Reply:A fully functional Syncrwave 250 is capable of welding thin sheet metal. You may need some practice to become proficient in welding thin sheet metal. Good fit up makes a big difference, and an aluminum backer plate might help keep you from burning through.Best of luckAirco 250 ac/dc Heliwelder Square waveMiller Synchrowave 180 sdMiller Econo Twin HFLincoln 210 MPDayton 225 ac/dcVictor torchesSnap-On YA-212Lotos Cut60D
